storage towers, one ground storage tank, a
pump station, and 200+ miles of water mains.

flushing dead-end water mains, regularly
replacing meters, and exercising valves throughout the network. Water is routinely
sampled from various sites throughout the city and tested for chlorine residual and
bacteria. Samples are also tested for lead and copper. The Engineering Division
oversees the construction of water infrastructure delivery system components to make
certain that improvements meet Colleyville Development Standards. These standard
practices ensure the delivery of clean, pure water to citizens.

maintenance program. These operations include cleaning and inspecting 180 miles of
